I wonder if is possible to buid a simple centripetal ( or centrifugal?) brake on the rear axle, of course adjustable. Now some motors have the power but not the brakes; if we could disjoin power from brakes, cars will be more easily driven in races.
If feasible, I think it will be far more useful than differential!!
